Paper Abstract

We report on the detection of a loss-inducing perturbation with variable localization accuracy along a test fiber based on the analysis of transmitted and reflected powers of an unmodulated continuous-wave light source. The required accuracy of localization is provided by suitable distribution of the differential reflectivity along the fiber. We demonstrate a localization accuracy equal to ±1.0 m along the 3.939-km single-mode test fiber for the strong perturbation and ±5.0 mm along a designated 10-cm fiber part for weak perturbation.
